The present invention relates to display devices such as OS terminals, and particularly relates to improvements in display devices whose display units can be replaced.

(2) Background of the Technology In recent years, PO8 terminals have been widely used in stores such as Tepart, supermarkets, etc. with the spread of conveter network systems.

The PO8 terminal is operated by an operator such as a clerk,
In addition to the register function, sales information by song item is sent online to the computer center for sales aggregation, island management, etc.
It functions as a terminal for an information management system that comprehensively performs product management such as purchasing management and store management. The apparatus is equipped with a display unit, and a predetermined display is performed based on information input by an operator through a keyboard operation ring. Other operational instructions to the operator are also displayed, such as the product number, product name, and price. Depending on the content to be displayed and the amount of display, a light emitting diode, a fluorescent display tube, a plasma display, or the like is used as the display panel of the display unit.

(3) Prior art and problems Figure 1 illustrates a PO8 terminal to which the present invention is applied.
8I is a perspective view. 2 is a side view of FIG. 1, and FIG. 3 is an exploded perspective view of the display section of FIG. 1.

In the figure, 1 is a PO8 terminal, 2 is a housing, 3 is a display section, 3a is a screen, 4 is a keyboard section, 5 is a receipt output port, 6 is a printer section, 7 is a winding section, 8 is a control section, 9 10 is a geared drawer, 10 is a frame, 11 is a printed board unit, 12 is a display panel, 13 is a display unit, 14 is a cover, and 18 is a screw. As shown in Figure 1, 1) O
The S terminal has a display section 3 arranged on the front side of the housing 2, and a keyboard section 4 installed at the center of the front side. Below the keyboard part 4 is a gear sock drawer 9.
A receipt outlet 5 is also arranged below the display section 3. As shown in FIG. 2, a control section 8 is disposed behind the keyboard section 4, to the right in the figure, and a printer section 6 is disposed above the control section 8.

A winding section 7 is provided at the front of the printer section 6.

The display section 3 has a V-shaped frame 10 as shown in FIG.
A display unit 13 consisting of a printed board unit 11 and a display panel 12 is installed in several places, and the front side of the display unit 13 is covered with a transparent cover 14 and fixed with screws 18. The printed board unit 11 is screwed to the frame 10, and the display panel 12 has its edges pressed against the frame 10 with a cover 14.

With this configuration, signals are sent to the control unit 8 based on input information such as operations on the keyboard unit 4 by operators I/-Y, and command signals from the control unit 8 are used to display product numbers, product names, and single-screen operators. The operation instructions are sequentially displayed on the screen 3aVC of the display unit 3, and after the amount is determined, necessary counting processing is performed and the total amount, change amount, etc. are displayed. At the same time, the printer section 5 prints the receipt and the journal, and the printed receipt comes out from the receipt outlet 5. The twisted journal is wound up by the winding section 7. Next, the cash drawer 9 opens and comes forward, so that cash can be dispensed and disbursed (2'). During this time, if there is a mistake in the operator's operation, a message such as ``BLUE'' is displayed on the screen 3a to help correct the processing error.

The display unit 3 of the display section 3 uses display panels 12 with different glazed display methods as described above. Since the unit 13 is fixed to the frame 10 with VC screws or the like, it is not easy to replace the display panel 12 with a different type of display panel 12.

Since the types of products displayed on the PO8 terminal differ significantly depending on the product sales floor, a display method corresponding to this is used when installing the terminal. For example, the types of products in the shoe department and the toy department are different, and the display panel 12 of the PO8 terminal used in the shoe department is of a light emitting diode type, and if the display panel 12 is of a light emitting diode type, a screen with the specified product name etc. will be displayed at a predetermined position on the screen 3a. However, a light emitting diode type display panel 12 in the gift shop would not be sufficient, so a plasma display type that can display any product name, etc. at any position on the display panel 12 is appropriate. It is.

However, in the distribution industry where PO8 terminals and the like are used, layouts are often changed due to expansion or relocation of product sales areas, and this often requires an increase in the number of items handled or a change in display content. Therefore, it was desirable that the display panel 12 of the PO8 terminal could be easily changed to a different system. (4) Purpose of the Invention The purpose of the present invention is to meet the above-mentioned needs, and to replace the display unit. is to provide an easy display device.
